Creation of the respiratory and the cardiac motion model.

<p>Example of real time images (a, b, c) and right hemi-diaphragm (RHD) navigator signal (d) acquired in one healthy adult subject. Four points (blue dots in a, b, c) were manually tracked over each 2D image to build up a model of the cardiac contraction. The RHD motion was used to generate a model of the respiratory motion of the heart.
